Robertson’s (defendant) son Brad visited Robertson in 1988 during Brad’s spring break from school. Brad was overweight but had become anorexic and bulimic once he realized that he could lose weight by vomiting and not eating. While with Robertson, Brad was brought to a doctor, who thought that he looked healthy but should return for a checkup within the month. Brad never returned for this checkup and continued to lose weight while in Robertson’s care. After a few months, Brad returned home to his mother, and was found dead in his sleep his first night home due to cardiac failure stemming from starvation. Robertson was charged with and convicted of involuntary manslaughter for his role in Brad’s death. Robertson appealed his conviction, claiming that the evidence was insufficient to sustain a conviction.
